Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Michinmahuida
Glacier-covered Volcán Minchinmávida is elongated along a NE-SW direction. The volcano has a mostly obscured 3-km-wide caldera, and a youthful eruptive center is located on the ENE side of the complex. An eruption from Minchinmávida was reported in 1742. Darwin observed the volcano in activity in 1834 on his renowned voyage that took him to the Galápagos Islands. NASA Space Station image ISS006-E-42260, 2003 (http://eol.jsc.nasa.gov/).
